How to get the distinguished name (DN) of the current host directly in adedit?

I know how to get the DN from the command line:

adquery user -D "$(hostname -s)"

However, I want to get the DN into an adedit script. If I can select_object {DN here}, then I can do the other things I need to do.

I just don't know how to get the DN directly in adedit.

According to the adquery man page (part of the Centrify Suite):

The adquery command is provided for backward compatibility to enable you to query Active Directory for information about users and groups from the command line on a Centrify-managed computer. You can use this command to query information for classic or hierarchical zones. In most cases, however, you should use adedit commands or scripts to query Active Directory for information in hierarchical zones.

However, there is no clear documentation I can find on how to translate adquery commands into native calls within adedit.

For example:

adquery user `hostname -s` --dump

This gives a list of all the raw attributes and values for the user that is the computer I'm running the command on. Using the --attribute flag, I can return just one attribute.

With adedit, after I've run select_object THE_DN, I can get other fields such as "description" by running get_object_field description. But, how to get the DN in the first place?

I've found the adedit programmer's guide, but can't find what I need in there despite extensive digging and experimentation.

Until I get a better approach, I am running:

adedit myscript "$(adquery user -D "$(hostname -s)")"

And then in the script:

if { $argc != 1 } {
  puts "format: $argv0 hostDN"
  exit 1
}

set the_dn [lindex $argv 0]

bind ... (credentials here)

select_object $the_dn

(Note: adedit is built on Tcl, so I've tagged this question Tcl as well as Active Directory. I don't have the reputation to create a Centrify tag.)
